China and India lead the way in “greening” the Earth since 2000

Given that plants are a huge natural carbon sink, a greener Earth can only be a good thing, right? That’s true in theory, but in practice different plants play different roles in the carbon cycle, so the increased greens might not necessarily slow down climate change. New forests are good for carbon capture, but new croplands tend to release any captured carbon back into the atmosphere at harvest time.
